New galaxy simulations could help reveal the origins of the Milky Way and provide clues in the decades-long search for dark matter, researchers say.

Towns and cities create an orange glow on the horizon at night. It's so widespread that it even disturbs sea creatures.

New models could inform researchers working to get the very first picture of Sagittarius A*, the supermassive black hole at the Milky Way's center.

The Milky Way may be catapulting stars into its outer galactic halo, researchers say. The finding could change how we think about how star systems are born.

"This is the first time we have been able to determine when such a merger happened."

A new composite image of the Milky Way appears to contain a cosmic candy cane.

"The velocity of the discovered star is so high that it will inevitably leave the galaxy and never return."

New research puts Einstein's theories of relativity to the test in a unique laboratory—the black hole at the center of the Milky Way.

Astronomers have the first look at a region of the Milky Way with molecular clouds about 180 light years across with 100,000X the mass of our sun .

"This discovery dramatically changes our view on the origin of fast-moving stars..."
